– Allow manual control over ISO 9141 and ISO 14230 initiation
– Added 4800 baud ISO 9141 and ISO 14230 support – Added extended addressing mode for CAN protocols – Added Low Power mode (‘sleep’ function) – Added wiring checks for when the J1962 CAN pins are used for other functions – Added ability to state the number of responses desired – New and commands for storing of unique identifier – Introduced LV RESET message for resets from low voltage – New STOPPED message for user interrupts during searches – Added space character control in responses – New CAN D0/D1 commands for printing of message dlc
– New CAN CRA commands to help setting masks and filters – Adaptive Timing tuned a little differently – Added check to prevent CAN mask corruption on certain Flow Control sends – Changed error detection to catch KWP 4 byte headers if no data or checksum – Modified KWP protocols to allow four byte headers – Added user defined CAN protocols B and C – Programmable Parameters can be reset with a jumper
– RS232 baud rates are adjustable to 500 kbps – J1850 VPW timing adjustment for some ’99 – ’00 GM trucks. The RS232 baud rates were only 9.6 kbps or 38.4 kbps Initial public release, the ELM327 v1.0 supported: The actual functions of these copies are nonetheless limited to the functions of the original ELM327 v1.0, with their inherent deficiencies. The problems reflect bugs that were present in ELM's version 1.0 microcode those making the clones may continue to sell the old version.Īlthough these copies may contain the ELM327 v1.0 code, they may falsely report the version number as the current version provided by the genuine ELM327, and in some cases report an as-yet non-existent version. ELM327 copies were widely sold in devices claiming to contain an ELM327 device, and problems have been reported with the copies. Pirates could trivially produce an ELM327 clone by purchasing the same microcontroller chip and programming it with the copied blob. Consequently, anyone who had bought a genuine ELM327-v1.0 could use a device programmer to read ELM's proprietary microcontroller firmware as a binary blob. When ELM Electronics sold version 1.0 of its ELM327, it did not enable the copy protection feature of the PIC microcontroller.

The ELM327 is a PIC microcontroller that has been customized with ELM Electronics' proprietary code that implements the testing protocols. Typical cheap ELM327 copy without label on the controller The ELM327 command set is similar to the Hayes AT commands. Oxygen sensor voltages/associated short term fuel trims.Clear some trouble codes and turn off the MIL ("Malfunction Indicator Light", more commonly known as the "Check Engine Light").Read diagnostic trouble codes, both generic and manufacturer-specific.

The function of such software may include supplementary vehicle instrumentation, reporting and clearing of error codes. There are a large number of programs available that connect to the ELM327. The ELM327 abstracts the low-level protocol and presents a simple interface that can be called via a UART, typically by a hand-held diagnostic tool or a computer program connected by USB, RS-232, Bluetooth or Wi-Fi.
